Summary: If you open Maps.app (or an app that uses Google Maps) on the iOS simulator, the simulator performance seems to be just a few frames per second (around 1 or 2 frames per second). This was not the case in Xcode 9 beta 3. Steps to Reproduce: 1. Open the Xcode 9 beta 4 simulator 2. Launch Maps.app 3. Pan around Expected Results: You get somewhere between 30 and 60fps on your macOS machine Actual Results: You get about 1 or 2 fps. Version: Xcode 9 beta 4 Notes: - This is not a problem in Xcode 9 beta 3 - Attached is a `simctl diagnose` a `simctl io booted enumerate` and a `sysdiagnose -q`
